The condition of her body initially led investigators to believe she had been killed by a wild animal, but investigators later determined it was a homicide.

RCMP announced on Thursday they arrested a male in Garden Hill in connection with the case, but they did not provide further details.

"While we understand that this arrest will generate a lot of questions, we are not in a position to provide further information at this time as there are a number of investigative steps currently being undertaken," Sgt. Bert Paquet said in a news release.

RCMP said further information about the arrest would be provided on Friday.

They requested voluntary DNA samples from men between the ages of 15 and 66 and hoped to collect 2,000 samples. RCMP never revealed how many samples were actually collected.

Manitoba Keewatinowi Okimakanak (MKO) said it is working with community leaders in Garden Hill.

"Your loss is tremendous and our hearts and prayers are with you at this time. While the circumstances are very difficult, I hope that this new information may help bring some closure for the family and the community," said MKO Grand Chief Sheila North Wilson.
